device of greatstrengtli and durability, de

signed for use on variouskinds of railways, either steam or electric, and adapted to be autoi'natically operated by various kinds of signals, and capable of positively causing a. train to stop. I

With these and other objects in view, the

invention consists in the construction and novel combination. of parts hereinafter fully describeil, illustrated in the accompanying drawings and pointed out in the claims herc to appended; it being understood that vsrious changes in the fOIIH, proportion, size and minor details of mnstruction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings:Figure 1 is a perspective view oi an air brake operating device, constructed in iiccordanee with this invention. Fig. 2 is a vertical sectional view, illus-' trating the manner of mounting the air brake operating har or-inember. Fig. 3 is-a diagrammatic view, showing the device applied to an electric signal. Fig. 4 isle sectional view, showing a motor connected with the air brake operating bar or member. Fig. 5 is an elevation showing thedevice applied to s semaphore.

Like numerals of reference designate corresponding parts in all the iignres of the drawings. 1

l designates an air brake operating her or member, preferably consisting of a. netallic rod, pivoted at an intermediate point to a suitable support by means of a pin 2, or other suitable festcnin device, and having its inner portion prei'orably arranged within s metallic casing 3, which constitutes the sup port for the brake operating bin" or member. The casing is rectangular in section and is l horizontal or operative position..

provided at its upper portion with s slots,

,through which the brake operating bar or member extends. The inner arm 5, which is shorter than the outer arm of the brake operating bar or member, is provided with. an ad justable counter-balancing weight 6, having an opening to receive the arm, and secured to the same by a set screw 7, or other suitable fastening device. The weight 6 is adapted to partially counter-balance the outer srm, which is adapted to swing downward to' sv horizontal position by gravity, when released. In Fig. 1 to 3 inclusive, the air brake operating bar or member is electrically operiited, and is designed to operate autometically in connection with block signal 8, but it may be eniployedin connection with any form of signal, either electrically or. mechanically operated. The hort arm 5 is provided with a curved armature 9, which is arranged to be actu eted by an electro magnet 10 for holding the outer arm of the brake operating bar or member normally in the elevated or inoperative position, illustrated in dotted lines in Fig. 3 of the drawings. The elect-r0 magnet is arranged in s circuit 11, having a suit-able battery 12 and pro-- vided with a circuit-breaker 13, arranged to be held closed. by the block signal 8, and adopted to automatically open, when the ssid block signal S swings to danger. -When the block signal 8 swings to danger and releases the circuit-breaker, the electro magnet 10 is denergized, and the air brake operating bar or member swings downward by gravity from the elcvated position shown in dotted lines in Fig. 3 to the operative position; illustrated in full. lines in the said figure. instead, however, of employing a supple mental circuit, as illustrated in Fig. 3, theair brake operating bar or member may he 7 connected with the circuit (not showiilfor actuating the block. signal 8.

As shown in Fig. 4, the short arm 5 of the brake operating bar or member may be con nccted by a cord 14 with a motor 15, adopted when the circuit is closed, to :wind up the cord and hold "the arm in an elevated position. When the circuit is broken, the motor shaft will be rotated by the weight of the; enter arm of the brake operating bar or member, which will swing downward to a.

sin

nected with the air brake system.

I The brake operating bar or member may, as illustrated in vFig. 5, be connected b a rod 16, or any other suitable means Witl a semaphore 17, or other form of mechanically when running backward, has a dc pending arm adapted to be oscillated by the air brake o crating bar or meniberr'whichextendsinto tne path of the arm and which may be an ranged to engage the same at diilerent points from the center of the cook or valve to secure the desired reduction of pressure in the train P the pressure within the train pipe is reduced, and the an? brakes are applied in the usual manner. This will not only stop the train but it will be necessary for the engineer or fireman to ieavel the cab and reset the cook or valve 1". l

' The air brake operating'bar or member is en orted in a horizontal or a roxin'iatel horizontal position by a vortica standard 20, having a crotch or recess 21 at'its upper end, which forms a scatter the outer arm of the air brake operating bar or ineinljier. The stand ard 20, which is mounted on a base 21 is' supported by opposite braces 22, and is do signed tb be constructed oi different lengths to arrange thecrotch or seat at the proper I. L a

nelght to suit the character of: the place where the signal is created, so that the air brakes-may be applied with a greater or less reduction of pressure. Thd'same result may,

Vihcn the cock or valve 18 is opened, l

combination with an air brake valve, of an sraoic however, be obtained by a vertically adjustable standard. I

Having thus fully described-my invention,

what I claim as new and desire to secure by Letters Patent, is

1. In a device of the. class described, the combination with an air brake valve, of a pivotally mounted operating arm arranged to'swing downward to a position for operating the said valve, and means arranged to receivothe arm at a point intermediate of the ends thereof for supporting the same when the said arm is in position for operating the valve 2. In a device of. the'class described, the combination with an air brake valve, of .a pivotallyniountcd air brake bar .or member, and a support provided with a vertical standard having a crotch to receive the bar or menibcr at a point intermediate of the ends thereof, a horizontal, base supporting the/standard, and inclined braces mounted on the base and located at opposite sides of the standard.

3. In a device of the class described, the

oscillatory air brake operating bar or member pi'votally mounted at an intermediate point and provided at one of its arms with a weight for counter-balancing the other arm,

a standard having a fork arrangcdtoreceive the latter arm, a signal, and means operated by the signal for automatically swinging the bar, or member to and from the standard.

Ii'i'te'stimony, that 1 claim the foregoing as my own,I have hereunto al'liXed my signature in the presence of two witnesses. WARREN PATTERSON. Witnesses:
